"European Union regulators are examining the contracts Apple strikes with cellphone carriers that sell its iPhone for possible antitrust violations after several carriers complained that the deals throttled competition." Well paint me red and call me a girl scout.

Yes, that is the quote, and I think you are projecting your own meaning on it. When the carrier rep says "that is not the case" I do not presume that he's referring to differences in contracts when he clearly hasn't seen the other contracts to speak of. I think it means: we are not dissatisfied and feel that Apple is acting in a monopolistic fashion.
